Grimm is a drama series inspired by the classic Grimm Brothers' Fairy Tales. After Portland homicide detective Nick Burkhardt (David Giuntoli) discovers he's descended from an elite line of criminal profilers known as "Grimms", he increasingly finds his responsibilities as a detective at odds with his new responsibilities as a Grimm.

Among Grimm's more immediate challenges are Giuntoli's initial blandness as its lead, along with questions regarding how long his confused partner ("Lincoln Heights'" Russell Hornsby) can continue showing up at crime scenes without ascertaining something's weird in the state of Oregon.

Grimm is most alive in the scenes where Nick teams up with Monroe (Silas Weir Mitchell), a monster who is trying hard to walk the straight path. These moments introduce some much-needed levity to a drama where every echoing slam of a file-cabinet drawer amounts to a portentous groan.

Grimm is neither a very strong police procedural nor a supernatural drama, as it sacrifices the intelligence required to construct smart, puzzling crimes in order to spend more time attempting to enunciate its fantastical elements, which aren't all that fantastical, with amateurish CGI.

There's a potentially good supernatural cop show to be made, and certain pieces in place to make this into that. But the version you'll see on NBC tonight seems to be embracing the show's likely failure by being something few will miss if it doesn't work out.

Grimm is buoyed by some decent special effects and snarky wolfman Monroe, who will be a series regular. But it's not nearly as imaginative, involving or picturesque as ABC's fairy tale offering, Once Upon A Time.

The byplay among the main characters is appealing, and the premise is solid and easy to grasp. The show does overplay its dread notes tonight, but there are also a few promising moments when Grimm shows a surprisingly subtle and even amusing touch.
